Calandiva is a type of Kalanchoe which has been developed to produce very double flowers in very tight clusters. This is a flowering house plant that should stay in bloom for a very long time. After flowering cut off spent flowers. Indoors keep it in a very bright light spot. Water as needed but keep it a little on the dry side. You an put it out for the summer but it needs a partial shade spot. It needs to be brought in for the winter before frost as it is not winter hardy in your area.
